Gravity iron casting on cheng casting

The component can be produced in either Aluminium or Zinc. Using a permanent mould called Gravity Die Tooling. Gravity iron casting are produced by molten metal entering an aperture in the Gravity Die Tooling, this aperture allows metal to enter the cavity to form the cast shape of the Gravity iron casting required by the customer.

Gravity iron casting produced in all grades of Aluminium and Zinc. Higher volumes of precision castings are achievable using the Gravity - Die Casting, external or internal is either produced by means of a purpose made steel core or as previously mentioned an Airset sand core.

Gravity iron casting produced are cost effective for quantities of a semi to high volumes. The finishing operations on a Gravity Die

Casting are minimal compared to a conventional sand casting, usually on a Gravity Die Casting the joint line is minimal and in some circumstances the need for an operation is not required.


Mechanical means are some times required for opening and closing of Die Tooling if the Gravity iron casting to be produced is large and complex.

Gravity iron casting if required by specification can be heat treated to adjust or improve its characteristics

Improvement to production rates of Gravity iron casting can be improved by the use of multiple tooling.

A Gravity Die-Tooling is able to produce Gravity iron casting for several years without the need of refurbishment
